With these additions, Delta will offer 160 peak-day flights to 49 destinations – including 16 of the top 20 destinations – from its Seattle hub this summer.

Flights to Austin and Nashville will operate using A319 aircraft, which have recently been upgraded and offer on-demand inflight entertainment for all passengers. Redmond and Eugene service will be operated by Delta Connection carrier SkyWest using two-class, 69-seat CRJ-700 jets. SkyWest will also operate Milwaukee service using an E-175 aircraft, while Delta will serve Lihue on a Boeing 757 and Raleigh on a Boeing 737 aircraft.

In addition to the new destinations, Delta will also expand service to existing destinations from Seattle. The airline will operate a second daily flight to Boston and Orlando, an eighth daily flight to Portland as well as a fifth daily flight to San Diego. Additionally, several flights to San Francisco and Denver will be upgraded to larger mainline aircraft.

On March 26, Delta’s joint venture partner Virgin Atlantic will begin Boeing 787 service from Seattle to London-Heathrow, replacing the flight currently operated by Delta and adding 50 seats as well as Premium Economy service.
